This earns a high rating simply for the gritty, persuasive performance from it's star, Isabelle Huppert, who is called upon to be a mother and an abortionist, to be a lover and a murderer, to be a free spirit and a prisoner of Nazi tyranny; Huppert may never gain your sympathy, and doesn't play for it, but she should gain your understanding as she plays a true-to-life story of a woman severely punished by the French government for a woman's crime that the dominant culture can not countenance because of the political atmosphere at the time--all this, and it's a gripping story,too--but not at all a cheerer-upper.
When you have finished watching this film, you may find Huppert's character hasn't quite finished with you, an observant, quiet reminder of the consequences of our actions. Hers is a haunting performance.
